Stability Properties of 1-Dimensional Hamiltonian Lattices with Non-analytic Potentials
Anastasios Bountis, Konstantinos Kaloudis, Thomas Oikonomou +2
We investigate the local and global dynamics of two 1-Dimensional (1D) Hamiltonian lattices whose inter-particle forces are derived from non-analytic potentials. In particular, we…
Periodically Forced Nonlinear Oscillators With Hysteretic Damping
Anastasios Bountis, Konstantinos Kaloudis, Christos Spitas
We perform a detailed study of the dynamics of a nonlinear, one-dimensional oscillator driven by a periodic force under hysteretic damping, whose linear version was originally prop…
Cauchy distributions for the integrable standard map
Anastasios Bountis, J. J. P. Veerman, Franco Vivaldi
We consider the integrable (zero perturbation) two--dimensional standard map, in light of current developments on ergodic sums of irrational rotations, and recent numerical evidenc…
Spatial Control of Localized Oscillations in Arrays of Coupled Laser Dimers
Joniald Shena, Yannis Kominis, Anastasios Bountis +1
Arrays of coupled semiconductor lasers are systems possessing radically complex dynamics that makes them useful for numerous applications in beam forming and beam shaping. In this…
Radically Tunable Ultrafast Photonic Oscillators via Differential Pumping
Yannis Kominis, Anastassios Bountis, Vassilios Kovanis
We present the controllability capabilities for the limit cycles of an extremely tunable photonic oscillator, consisting of two coupled semiconductor lasers. We show that this syst…
Enhanced stability, bistability, and exceptional points in saturable active photonic couplers
Yertay Zhiyenbayev, Yannis Kominis, Constantinos Valagiannopoulos +2
A generic photonic coupler with active and lossy parts, gain saturation and asymmetric characteristics is examined. Saturable activity is shown to be able to enhance the overall st…
